Possible legitimate sources could be academic libraries, interlibrary loan services, or free public libraries. Some platforms like Google Books or Amazon might let you preview the content. Also, there might be open educational resources (OER) that are alternatives to the book. I should mention those.
Let me structure the response step by step. First, explain what the book is. Then discuss copyright issues. Next, provide legal ways to access it. Finally, suggest alternatives if the book isn't available freely. Make sure to keep the tone helpful and not judgmental, offering practical solutions instead of just saying no.
I should check if the book is available through legal free sources, like the publisher's website offering free chapters or sample pages. Maybe the author or publisher has made some content freely available. If not, the user might be looking for torrent links or other illegal sources, which I can't support. I need to guide them away from piracy and towards legal alternatives.
